Building Microservices with Quarkus
What you'll learn
- Understand the MicroProfile ecosystem and how Quarkus supports it
- Bootstrap two Microservices with Quarkus
- Develop, configure and test each microservice separately using JAX-RS, JSON-B, CDI, JUnit and RestAssured
- Use MicroProfile OpenAPI to document each microservice
- Use MicroProfile REST Client so microservices can communicate with one another
- Use MicroProfile Fault Tolerance so the communication between microservices can gracefully handle failure
- Generate native binaries thanks to GraalVM
- Build and execute Docker containers for each microservice
- Bundle both microservices into a single Docker Compose file and configure it so the entire system is executed with a single command
Requirements
- A recent Windows / Mac / Linux machine
- Knowledge of the Java language and the Java ecosystem (Maven, JUnit, GraalVM)
- Basic knowledge of Quarkus
- Basic knowledge of Microservices
- Basic knowledge of RESTful Web Services
- Basic knowledge of Docker
Description
This course is for Quarkus developers who want to discover how Quarkus and MicroProfile handle microservices. It’s a mixture of slides and code so you can “Understand and Practice” at the same time. This way, you learn the theory, and then put it into practice by developing a microservice architecture step by step.
In this course you will develop two microservices that talk to each other. After introducing Microservices and MicroProfile, you will make sure your development environment is set up, and you will go from bootstrapping two Quarkus microservices, to running them as Docker containers. The different steps you’ll go through are:
Understand Microservices,
Understand MicroProfile,
Check your development environment,
Develop two microservice that expose a REST endpoint using JAX-RS and CDI,
Customize the JSON output with JSON-B,
Test the two microservices in isolation with JUnit and RESTAssured,
Configure each microservice,
Document each microservice with MicroProfile OpenAPI,
Establish the communication between microservices with MicroProfile REST Client
Mock the microservice communication when testing,
Handle communication failure with MicroProfile Fault Tolerance,
Build a Linux executable with GraalVM out of each microservice,
Containerize each microservice with Docker and execute it,
Create and configure a Docker Compose file so both microservices can be executed in a single command.
At the end of the course you’ll get a good understanding on how implementing microservices with Quarkus. You will be able to bootstrap, develop, package and execute a microservice architecture, but most important, take Quarkus microservices to your next project.
Good luck for the course, and please reach out if you need any help or if you have any request: I’m here to help!
Who this course is for:
- Java developers who know Quarkus
- Quarkus developers curious about microservices
- Back-end Java developers willing to move to microservices
- Spring Boot or Micronaut developers wanting to compare their toolkit with Quarkus
Instructor
Antonio Goncalves is a senior developer living in Paris. He evolved in the Java EE landscape for a while and then moved on to Spring, Micronaut and Quarkus. From distributed systems to microservices and the cloud, today he helps his customers to develop the architecture that suits them the best.
Aside from freelancing, Antonio wrote a few books (Java EE and Quarkus), talks at international conferences (Devoxx, JavaOne, GeeCon…), writes technical papers and articles and co-presents on the Technical French pod cast Les Cast Codeurs. He has co-created the Paris JUG, Voxxed Microservices and Devoxx France. For all his work for the community he has been made Java Champion ten years ago.
